This 'invention relates to machines for making boxes and moreparticularly to 'maadapted for use in boxes in which it is inchines formaking paper boxes. 7

It is the object of the invention to provide a machine for automaticallyproducing trays having reinforced endsformed by doubling back upon theseends extensions provided along the top thereof. It is also preferable tohaveextensions on the adjacent sides of the tray, which extensions areoverlapped with the ends and inclosecl by foldingor bending the topextensions of the ends over them.

The novel features of the invention will be apparent from the followingdescription taken in connection with the accompanying drawings, inwhich, 7

Fig. 3 is a plan view of the pasting mechanism; Y Fig. 4 is a verticalsection on the line 4- -4 of Fig. 3;

Fig. 5 is an end view of one of the plune 'gers, the die co6peratingtherewith. being the line 7 7 of Fig. 5;

Fig. 8 is a plan view of the material fromv which theboxes are made andshowing the.

manner offorming the blanks;

- Fig. 9 is a perspective view of a partially formed tray; and

Fig. 10 is a perspective view of the completed tray.

Referring to'Figs. 8, 9 and10, it will be seen that-the tray, as formedinthis macomprises the bottom portion 20,-the

chine end'walls 22. The sideside walls 21 and the walls 21 have endextensions23 which,when the box is completed are arranged on the innersurface of the endwalls 22. This is shown clearly in F 9. The end walls22 are prov1ded with top extensions 24. which are folded over theextensions 23, as; shown in Fig. 10. The extensions 23 areglued to 3 ifV the inner surface 'of the "ends 22 and also .to theextensions 24:. Inthisway a-tray is ,provlded n which the ends are formed of threethicknesses of material with two layers of glue and when the gluehardens averystiif end. results which makes the tray especially traysare formed simultaneously and suit- V able d e ng mechanism isprovidedifor slot- 7 ting-the web ofmaterial a at the points I)Thejcompleted blanks are shown at the left side of Flg. 8 and'the dottedlines indicate the creases in the blank and the full linesi indicatethe'cuts. s

The dieing and creasing mechanism is in dicated diagrammaticallyin Fig.1 at A and the detailsof this mechanism may beof any preferred form,such as the form described andjillustrated in the Inman Patent No.1,067,253.

The portions of the blanks forming the end walls 22 and the extensions24: thereof have an adhesive material, such as a suitable paste orglue,app'lied thereto and in accordance with the'present invention Iapply this adhesive material. to the upper surface of the blank. It willbe understood that-suitable feeding mechanism for the-web will beprovided, as fully described; inthe aforesaid Inman Patent No. 1,067,253and this feeding mechanism will give an intermittent forward movement tothe web. In order toapply the glue to the uppers'urface of the blankthereis arranged above the path of. the web a glue receptacle 25 whichis supported on brackets 26 and has arranged therein .a roll 27 forfeeding theglue from, thereceptacle. A roll 28, journaled in thebrackets 26, has oppositely arranged .pads 29 thereon adapted toengage'theblanks and apply the glue'thereto. The roll 28 has in.coiiperation therewith a roll .30 arrangedber low the web and which actsas a platen to support the web while the pads 29 are in; engagementtherewith. A roll 31, j ournaled in suitable brackets 31, engages thesurface V {roll 28 rotates and thus transfers the glue from the roll 27,to the pads 29. The pasting or gluing mechanism just described is intermittently operated by means of a chain 32 which is preferably driven bythe web feeding mechanism (not shown) and which op. eratively engages asprocket 33 on the v of the roll 30. The chain 32 also passes over asprocket 34 which drives the feeding mechanism 35, this mechanism beingsimilar to the corresponding feeding mechanism shown in the Inman patentabove referred to. The rolls 28 and 31 are preferably drivenfrom theroll30 by means ofsuitable gearing 36, so that these rolls will bepositively driven in accordance with the'feeding movements of'the web.'7

After passing throughthe pasting mechanism just described and also thefeeding mechanism 35, the blanks are received by the forming mechanismB. Theblanksare severed from the web in any suitable man-1 ner, such aslllustrated 1n .the aforesaid Inman patent. The forming mechanismcomprises upright brackets 37, secured to r the frame 38 of the machineand supporting trated'in' Fig. 1 and comprises the recipros eating rack41 which has its lower end connected with the rotating crank disk 42.The plungers ,40 cotiperate with dies 48, these dies havingmovable sides44 and a yieldable bottom 45. The dies 43 and movable sides 44thereofare provided, at the corners of the blank opening, with blocks 43 whichare generally similar to'the blocks a of the Inman Patent No. 996,086and cooperate with the plunger in the manner hereinafter 7 described.Thedetails of the plungers and dies are shown in Figs. 5, 6 and 7 andthe normal'position ofthe yieldable bottom 45 of the dies issubstantially on a level with thetop of the side walls of the dies. In

7 Figs. 5 and 6 the bottom 45 is shown in the Y depressed position. Thebottom 45 has secured thereto apair of vertical slide rods 46 which arearranged in tubular guides 47 secured to the stationary bottom walled ofthe dies. These tubularguides 47 have their upper ends so positioned astov be engaged byithe'yieldablefbottom 45 to limit the downward movementof the latter, as shown in F gs. 5 and 6. Springs. 49 are v coiledvaboutftheguides 47 and normally tend to press the bottom 45 upwardlythe upward mot on being limited by collars 50 011 the lower ends of therods 46, these collars engaging the underside of the wall 48. V

The plungers 40 each comprise a hollow body portion in which rods 51 areslidably supported. These rodshavesecured to the lower ends thereof aplate 52 which serves asthe bottom wall of the plunger. Springs 53 arecoiled about the rods 51 and engage collars 54 on the rods and apartition 55 across the plunger and thus normally press the rodsdownwardly, the downward'move ment being limited by the engagement ofthe collars 56 with the upper surface of the partition 55. There arealso secured on the rods 51brackets57 to which are pivotally connectedthe wings 58. These vwings have horizontal pivots, and springs 59. arepro I vided forrswinging these wings outwardly from the'position shownin'Fig.6. The springs 53 have greater tension than the springs 49' sothat when the plunger descends and the plate 52 engages the plate45,

the latter will yield. -When the plunger is in the elevated position,thespring's 53 force the rods 51 downwardly to position where it thecollars 56' engage the-partition 55 and in this position the wings'58stand a"substantially horizontal position. 7

The operation is as follows:

over'the' die 43 and the plunger descends and the portion of the blankwhich forms.

the bottom of the boX is engaged by the plates 45 and 52 and the blankcarried into the die to the position shown in Fig. 6, the

of the forming mechanism a 1 The blanks are fed to a position directly"blocks 43 turning theextensions 23 against 7 the inner/sides of the endwalls of the'bor;

so that as the plunger descends the exten-' sions 23.w1ll be arrangedasshown 1n Fig, 9.

On account of the springs 53 being of greater tension than the springs49 the latter yield when the plate 52 engages the blank. Theplate 45,being, in Fig. 6, at the limit of its downward'movement, the move mentof the plate 52 will be interrupted and the plunger" body will then;move independently, the springs 53 being thereby compressed. As theplunger body descends" while the rods 51 are held stationary, it

pushes the wings 58 downwardly so that they swing. about their pivotalconnections with the brackets 57 and engage the exten sio ns 24 of theblank and swing these extension's inwardly'to' a substantiallyhorizontal position, downwardmovement and, engagingthe ex tensions 24,carries the latter to their final position, shown in'Fig. 10. The limitof the downwardmovement of the plunger body' is slightly above the plate.52 and after {the plunger body reaches this limit the 'mov The plungerbody continues its.

able side 44 of the die is moved against-the box; so as to compress theoverlapped por'- tions, forming the end walls offthebox, to

After the overlapped portions of thebox have been pressed together, bythe movable side 44 of the its initial position and the plungerwithdrawn. At first only the plunger body moves upwardly untilthecollars 56 engage V 55 and then the-plate 52 is the partition As theplate 52 recedes the withdrawn. springs 49 upwardly so as to carry thebox out of the die. The plate 52 movement until it reaches the positionshown in Fig. 2.

A bar 61, which serves as a rake to remove the finished boxes. isarranged above the dies, as shown in Fig. 2, and has connected with theopposite ends thereof rods 62 which are also connected with arms 63 on arock shaft 6% The rock shaft 64: carries an arm 65 having a roller 66 onthe lower end thereof and arrangedfito be enmounted on a shaft 68 whichis driven by V to bend the said top extensions whereby the any suitablemechanism, in timed relation 7 with the movements of the plungers sothatthe rake will operate to remove the fin shed boxes after each upwardmovement of the plungers.

It is evident that the invention may be in other forms of mechanism thanV embodied that shown and described and therefore I do not wish to belimited to the exact details shown. t
